The command "netsh interface ipv4 dump" does not export the subnet mask setting in Windows 7, in Windows Server 2008 R2, in Windows Server 2008, and in Windows Vista


View products that this article applies to.

Symptoms

Consider the following scenario:
  • You use the netsh interface ipv4 dump command to export and back up the persistent configuration settings for the network interface on a computer that is running one of the following operating systems:
    • Windows 7
    • Windows Server 2008 R2
    • Windows Server 2008
    • Windows Vista
  • You import this backup of the configuration settings.
In this scenario, an incorrect subnet mask is set.

Note The Netsh command can output the script for the network configuration settings of the computer. By using this command, you can copy the script so that you can run the script to restore the settings if you reinstall the operating system.

Cause

This issue occurs because the information about the subnet mask is not exported when you run the netsh interface ipv4 dump command. Therefore, an incorrect subnet mask is set when you import the backup of the configuration settings.

Windows Vista and Windows Server 2008 file information notes
Important Windows Vista hotfixes and Windows Server 2008 hotfixes are included in the same packages. However, only "Windows Vista" is listed on the Hotfix Request page. To request the hotfix package that applies to one or both operating systems, select the hotfix that is listed under "Windows Vista" on the page. Always refer to the "Applies To" section in articles to determine the actual operating system that each hotfix applies to.
  • The files that apply to a specific product, SR_Level (RTM, SPn), and service branch (LDR, GDR) can be identified by examining the file version numbers as shown in the following table.
    VersionProductSR_LevelService branch
    6.0.600 1 . 22xxxWindows Vista and Windows Server 2008SP1LDR
    6.0.600 2 . 22xxxWindows Vista and Windows Server 2008SP2LDR
  • Service Pack 1 is integrated into the release version of Windows Server 2008. Therefore, RTM milestone files apply only to Windows Vista. RTM milestone files have a 6.0.0000.xxxxxx version number.
  • The MANIFEST files (.manifest) and the MUM files (.mum) that are installed for each environment are listed separately in the "Additional file information for Windows Server 2008 and for Windows Vista" section. MUM files and MANIFEST files, and the associated security catalog (.cat) files, are extremely important to maintaining the state of the updated component. The security catalog files, for which the attributes are not listed, are signed with a Microsoft digital signature.

Workaround

To work around the issue, add the correct subnet mask to the configuration settings that you exported. When you import the configuration settings that you modified, the Netsh command adds the correct subnet mask.

Status

Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.

More information

The following is a sample of the output for the netsh interface ipv4 dump command when this issue occurs:
------------------------------------
# ----------------------------------
# IPv4 Configuration
# ----------------------------------
pushd interface ipv4

reset
set global icmpredirects=enabled
add route prefix=0.0.0.0/0 interface="Local Area Connection" nexthop=<IP>
add address name="Local Area Connection" address=<IP> 

popd
# End of IPv4 configuration

For example, assume that you have defined a subnet mask of 255.255.254.0 in your static IP v4 configuration settings. In this scenario, the following are the two possible expected results for the line that has the "add address" text in the output:
  • add address name="Local Area Connection" address=<IP Address> mask=255.255.254.0
  • add address name="Local Area Connection" address=<IP Address>/23
